Google Talk Guru answers questions via your IM app

Just add guru@googlelabs.com to your GTalk buddies, and you can start firing off questions. Lifehacker suggests that the same types of queries supported by Google SMS will work, though we didn't have any luck getting a response out of the Guru with phrases like "score detroit red wings" or "sushi R3N 1Y1."

Still, Guru does answer a good variety of questions and it works right within your favorite IM app. It's well worth adding to your friend list, especially for getting answers on the go on your mobile device of choice.
